O que significa o código δ5 para as propriedades mecânicas dos materiais?
Reply #22016-09-24
A taxa de alongamento após ruptura δ5 refere-se ao caso em que o comprimento do trecho da barra de teste é igual a 5 vezes seu diâmetro (comprimento de medida curto); esse é o método de medição utilizado nos padrões antigos. Agora, a taxa de alongamento em condições de ruptura é expressa por A (%).
